MotorStorm: Arctic Edge will release in UMD format on Sept. 29 - delaying the downloadable version of the game until Oct. 1, just in time for the PSPgo's debut.

For those uninitiated, this MotorStorm takes the festival up to the land of the midnight sun, adding sno-cats and snowmobiles (sigh, snow machines) to the vehicle fleet. There's an early adopter bonus - buy it in the first 30 days on sale and you get a free Mirage Rapide rally car, plus two customizable skins, via PSN.
